Changes

St. Isaac is fully accepted as a saint in the Orthodox Church, though during his lifetime, he was [[canons (law)|canonically]] a member of the Assyrian Church of the East (i.e.the Persian Church), which eventually adopted doctrines similar to those of the [[Nestorianism|Nestorians]]). His writings nevertheless came to be extremely popular in Orthodox monastic circles and are well-known for their Orthodoxy. [[Veneration]] for him grew, and he came to be incorporated into the Orthodox calendar of saints. His inclusion is thus an indication that the Church does not regard [[canonical territory|canonical boundaries]] as being the litmus test of Orthodoxy.
